Key takeaways
  • Tarion warranties start on the date of possession and run one, two and seven years depending on the problem.
  • Maximum statutory coverage is $400,000 for freehold homes and $300,000 for condo units if the agreement was signed on or after July 1, 2023.
  • Deposit protection for freehold homes is up to $60,000 for prices of $600,000 or less, and registering your purchase agreement within 45 days gets the maximum cover.
  • Claim forms have deadlines, so mark them on your calendar from the day you take possession.

Buying a brand-new home comes with a warranty system that does not exist for resale homes. In Ontario, Tarion is the body that sets out the coverage for new homes, from your deposit before closing to defects after you move in.

This article explains the main parts: what is covered, for how long, the dollar limits and how claims work. Rules can depend on when you signed your agreement and Tarion has been under reform, so confirm the current details with your lawyer.

When the warranty starts and how long it lasts

Tarion warranties start on the date of possession, which is closing for a freehold home and interim occupancy for a condo. There are three layers of coverage:

PeriodWhat is covered
One yearWorkmanship, materials, Building Code violations and unauthorized substitutions
Two yearsWater penetration, electrical, plumbing and heating
Seven yearsMajor structural defects

Write the possession date on your calendar right away. Every deadline below is counted from it.

Coverage limits

The maximum statutory warranty coverage depends on when you signed your agreement. If it was signed on or after July 1, 2023, the limit is $400,000 for freehold homes and $300,000 for condo units. If it was signed from February 1, 2021 to before July 1, 2023, the limit is $300,000 for both.

These are maximums, not what you will necessarily receive. Whether a defect is covered, and how much is payable, depends on the facts and the warranty terms.

Deposit protection before you move in

Tarion also protects deposits. For freehold homes, protection is up to $60,000 when the price is $600,000 or less (agreements from January 1, 2018), or 10% of the price up to $100,000 when the price is over $600,000. Condo unit deposits are protected up to $20,000.

Registering the purchase agreement within 45 days gets the maximum cover. If you have just signed, ask your lawyer to confirm that registration is done.

Closing delays on a new build

Tarion also sets rules for delayed closings on freehold homes. Compensation is $150 per day for living expenses with no receipts, plus other receipted costs, capped at $7,500 in total. Less than 10 days' notice of a delay gives $1,500. You claim to the builder within 180 days and then to Tarion within the first year of possession, or 365 days after termination.

Closing-date changes generally need at least 90 days' written notice. If the home is not complete by the Outside Closing Date, 365 days after the Firm Closing Date, you have a 30-day termination period and get a full refund plus interest.

How to file a warranty claim

Warranty claims use forms with set timing: the Year-End Form in the last 30 days of year one, the Second-Year Form during year two, and the Major Structural Defect Form after year two and no later than year seven. Missing a window can put a claim at risk, so do not wait until the last day.

What to do next

Frequently asked questions

Does the Tarion warranty cover resale homes?

The coverage described here is for new homes, freehold and condo units, starting on the date of possession. A resale purchase is a different situation, so ask your lawyer what protection applies.

What does the two-year warranty cover?

It covers water penetration, electrical, plumbing and heating. The one-year warranty covers workmanship, materials, Building Code violations and unauthorized substitutions.

How much coverage can I get?

For agreements signed on or after July 1, 2023, the maximum is $400,000 for freehold homes and $300,000 for condo units. Earlier agreements, from February 1, 2021 to before July 1, 2023, have a $300,000 maximum for both.

When do I have to submit claim forms?

The Year-End Form is for the last 30 days of year one, the Second-Year Form is for year two, and the Major Structural Defect Form is for after year two and no later than year seven. Track these dates from your possession date.
